How the cash counter works
Instead of mentally multiplying each stack of notes and coins, this calculator
does the arithmetic for you. You simply enter how many of each denomination
you have and it:
- Multiplies each count by the denomination value.
- Sums all bill denominations.
- Sums all coin denominations.
- Adds everything together into a grand total.
The result is a clean total cash amount plus a breakdown by
bills vs coins and some helpful summary stats like total item count and average
value per item.
Supported denominations
The default layout uses a common pattern:
- 100s, 50s, 20s, 10s, 5s and 1s as bills.
- 0.25, 0.10, 0.05 and 0.01 as coins.
Because the calculator is unit-based, you can interpret these as any currency:
for example, 20 could be $20, €20, £20 or another 20-unit note. The
currency selector only affects symbols and formatting.
Step-by-step example: counting a till
Imagine you are closing a cash register and find the following:
- 5 × 20s
- 8 × 10s
- 4 × 5s
- 10 × 1s
- 16 × 0.25 coins
- 10 × 0.10 coins
Enter these counts into the calculator and it will show:
- The subtotal for each denomination (for example, 5 × 20 = 100).
- How much of the total comes from bills versus coins.
- The overall cash total in your chosen currency format.
Using the totals for reconciliation
The cash counter is especially handy for reconciling against an expected
amount, such as a POS system end-of-day figure or a float amount.
-
First, count your drawer and record the total from this calculator.
-
Compare it to the expected total from your system or float sheet.
-
If there is a difference, drill down into the denomination subtotals to look
for likely miscounts.
Because the calculator shows subtotals by denomination, it is easier to spot
where an extra note or missing coin might be hiding.
Tips for faster cash counting
-
Stack and straighten notes first. Stack notes by
denomination, all facing the same way, before counting. This reduces error.
-
Count coins in groups. For example, count quarters in
groups of 4 to quickly build whole units.
-
Count out loud. Saying totals as you enter them helps catch
slip-ups while typing.
-
Use the average value per item. An unexpectedly low or high
average can flag data entry errors.
Frequently asked questions
Can I add extra denominations?
This version includes a fixed set of common denominations. If you need extra
ones (for example, 2-unit coins or 200-unit notes), you can treat an existing
line as that value or duplicate the pattern in your own custom implementation.
Does the calculator handle negative values?
No. Counts are intended to be non-negative integers. Negative values would not
make sense in a physical cash count and are treated as zero.
Is the result stored anywhere?
No. The calculator runs entirely in your browser. Totals are not saved or
transmitted, so you should copy down the result if you need a record.
Can I use this for multiple tills or floats?
Yes. Many people open the calculator in separate tabs or windows for each till,
or record the result in a spreadsheet alongside an identifier for the drawer.
